LOW RESIDUE CLEANING SOLUTION
BY INVENTORS: Stephen Bradford Kong, Sonia H. Burciaga, and Andrew
Kilkenny
BACKGROUND OF THE INVENTION
Field of the Invention
[0001] The present invention relates generally to a composition and method for
reducing residue left by wet cleaning substrates used for cleaning hard
surfaces, such
as a kitchen, bathroom or other hard surface.
Description of the Related Art
[00021 When cleaning wipes are impregnated with cleaning compositions
containing
cationic biocides for disinfection, the cleaning operation typically leaves a
residue on
glossy surfaces. This may be the case because the saturated wipes leave
substantial
liquid on the surface. When using a spray cleaner, the residue problems are
reduced
since the consumer typically wipes off the spray cleaner with a dry paper
towel. It is
the combination of the cleaning substrate saturated with the cleaning
composition that
makes it difficult to leave a surface free from filming and streaking.

[0003] U.S. Pat. 6,936,580 and U.S. Pat. 6,716,805 to Sherry et al. discloses
alkylpolyglucosides with hydrophilic polymers and propylene glycol propylether
on
nonwoven substrates. U.S. Pat. 4,753,844 to Jones et al. discloses alkylpoly-
glucosides, ethanol, and isopropanol on nonwoven substrates. U.S. 5,342,534 to
Skrobala et al. discloses alkylpolyglucosides and ethanol on nonwoven
substrates.
U.S. Pat. App. 2005/0121054, and U.S. Pat. 7,082,951 to Barnabas et al.
discloses
alkylpolyglucosides with citric acid and PHMB.
[0004] The present invention surprisingly has found a liquid cleaning
composition
containing a quaternary biocide that when absorbed onto a nonwoven substrate
provides surface disinfection with low residue (low filming and streaking) and
low
foaming during use. The low foam translates to lower filming and streaking and
thus
significantly improves consumer acceptability for a disinfecting wipe. While
not
intending to be bound by theory, the premise for achieving low filming and
streaking
is to have a cleaning composition that does not bead up (i.e. having no
increase in
contact angle as the composition dries). The choice of surfactant and solvent
significanly affects the properties of the formulation as it dries. Most quat
based
disinfecting wipes products leave significant residue that is particulary
noticeable on
smooth glossy surfaces. The inventive formulation provides surface
disinfection and
cleaning while providing low foaming and low residue (i.e. low filming and
streaking), thus eliminating the need of a follow up wiping step. The problems
associated with residue left after cleaning with wet substrates of the prior
art can be
avoided by the low residue compositions of the present invention. It is
therefore an
object of the present invention to provide an antimicrobial cleaning
composition in a
cleaning substrate that overcomes the disadvantages and shortcomings
associated with
prior art examples.

Water
[0039] When the composition is an aqueous composition, water can be, along
with
the solvent, a predominant ingredient. The water can be present at a level of
less than
99.9%, or less than about 99%, or less than about 95%. The water can be tap
water,
soft water, or deionized water. Where the cleaning composition is
concentrated, the
water may be present in the composition at a concentration of less than about
85
wt.%.
Substrate
[0040] The cleaning composition may be part of a cleaning substrate. A wide
variety
of materials can be used as the cleaning substrate. The substrate should have
sufficient wet strength, abrasivity, loft and porosity. Examples of suitable
substrates
include, nonwoven substrates, wovens substrates, hydroentangled substrates,
foams
and sponges. Any of these substrates may be water-insoluble, water-
dispersible, or
water-soluble.
[0041] In one embodiment, the cleaning pad of the present invention comprises
a
nonwoven substrate or web. The substrate is composed of nonwoven fibers or
paper.
The term nonwoven is to be defined according to the commonly known definition
provided by the "Nonwoven Fabrics Handbook" published by theAssociation of the
Nonwoven Fabric Industry. A paper substrate is defined by EDANA (note 1 of ISO
9092-EN 29092) as a substrate comprising more than 50% by mass of its fibrous
content is made up of fibers (excluding chemically digested vegetable fibers)
with a
length to diameter ratio of greater than 300, and more preferably also has
density of
less than 0.040 g/cm 3. The definitions of both nonwoven and paper substrates
do not
include woven fabric or cloth or sponge. The substrate can be partially or
fully
permeable to water. The substrate can be flexible and the substrate can be
resilient,
meaning that once applied external pressure has been removed the substrate
regains
its original shape.

WO 2008/079718 PCT/US2007/087451
[0042] Methods of making nonwovens are well known in the art. Generally, these
nonwovens can be made by air-laying, water-laying, meltblowing, coforming,
spunbonding, or carding processes in which the fibers or filaments are first
cut to
desired lengths from long strands, passed into a water or air stream, and then
deposited onto a screen through which the fiber- laden air or water is passed.
The air-
laying process is described in U.S. Pat. App. 2003/0036741 to Abba et al. and
U.S.
Pat. App. 2003/0118825 to Melius et al. The resulting layer, regardless of its
method
of production or composition, is then subjected to at least one of several
types of
bonding operations to anchor the individual fibers together to form a self-
sustaining
substrate. In the present invention the nonwoven substrate can be prepared by
a
variety of processes including, but not limited to, air-entanglement,
hydroentanglement, thermal bonding, and combinations of these processes.
[0043] Additionally, the first layer and the second layer, as well as
additional layers,
when present, can be bonded to one another in order to maintain the integrity
of the
article. The layers can be heat spot bonded together or using heat generated
by
ultrasonic sound waves. The bonding may be arranged such that geometric shapes
and patterns, e.g. diamonds, circles, squares, etc. are created on the
exterior surfaces
of the layers and the resulting article.
[0044] The cleaning substrates can be provided dry, pre-moistened, or
impregnated
with cleaning composition, but dry-to-the-touch. In one aspect, dry cleaning
substrates can be provided with dry or substantially dry cleaning or
disinfecting
agents coated on or in the multicomponent multilobal fiber layer. In addition,
the
cleaning substrates can be provided in a pre-moistened and/or saturated
condition.
The wet cleaning substrates can be maintained over time in a sealable
container such
as, for example, within a bucket with an attachable lid, sealable plastic
pouches or
bags, canisters, jars, tubs and so forth. Desirably the wet, stacked cleaning
substrates
are maintained in a resealable container. The use of a resealable container is
particularly desirable when using volatile liquid compositions since
substantial
amounts of liquid can evaporate while using the first substrates thereby
leaving the
remaining substrates with little or no liquid. Exemplary resealable containers
and
dispensers include, but are not limited to, those described in U.S. Pat. No.
4,171,047
18
CA 02672748 2014-04-02
to Doyle et at., U.S. Pat. No. 4,353,480 to McFadyen, U.S. Pat. No. 4,778,048
to
Kaspar et al., U.S. Pat. No. 4,741,944 to Jackson et at., U.S. Pat. No. 5,
595,786 to
McBride et al. The cleaning substrates can be incorporated or oriented in the
container as
desired and/or folded as desired in order to improve ease of use or removal as
is known in
the art. The cleaning substrates of the present invention can be provided in a
kit form,
wherein a plurality of cleaning substrates and a cleaning tool are provided in
a single
package.
[0045] The substrate can include both natural and synthetic fibers. The
substrate can
also include water-soluble fibers or water-dispersible fibers, from polymers
described
herein. The substrate can be composed of suitable unmodified and/or modified
naturally occurring fibers including cotton, Esparto grass, bagasse, hemp,
flax, silk,
wool, wood pulp, chemically modified wood pulp, jute, ethyl cellulose, and/or
cellulose acetate. Various pulp fibers can be utilized including, but not
limited to,
thermomechanical pulp fibers, chemi-thermomechanical pulp fibers, chemi-
mechanical pulp fibers, refiner mechanical pulp fibers, stone groundwood pulp
fibers,
peroxide mechanical pulp fibers and so forth.
[0046] Suitable synthetic fibers can comprise fibers of one, or more, of
polyvinyl
chloride, polyvinyl fluoride, polytetrafluoroethylene, polyvinylidene
chloride,
polyacrylics such as ORLON , polyvinyl acetate, Rayon , polyethylvinyl
acetate,
non-soluble or soluble polyvinyl alcohol, polyolefins such as polyethylene
(e.g.,
PULPEXO) and polypropylene, polyamides such as nylon, polyesters such as
DACRON or KODEL , polyurethanes, polystyrenes, and the like, including fibers
comprising polymers containing more than one monomer.
[0047] The cleaning substrate of this invention may be a multilayer laminate
and may
be formed by a number of different techniques including but not limited to
using
adhesive, needle punching, ultrasonic bonding, thermal calendcring and through-
air
bonding. Such a multilayer laminate may be an embodiment wherein some of the
layers are spunbond and some meltblown such as a spunbonclimeltblown/spunbond
(SMS) laminate as disclosed in U.S. Pat. No. 4,041,203 to Brock et al. and
U.S. Pat.
19
CA 02672748 2014-04-02
No. 5, 169,706 to Collier, et al. The SMS laminate may be made by sequentially
depositing onto a moving conveyor belt or forming wire first a spunbond web
layer, then
a meltblown web layer and last another spunbond layer and then bonding the
laminate in
a manner described above. Alternatively, the three web layers may be made
individually,
collected in rolls and combined in a separate bonding step.
[0048] The substrate may also contain superabsorbent materials. A wide variety
of
high absorbency materials (also known as superabsorbent materials) are known
to
those skilled in the art. See, for example, U.S. Pat. No. 4,076,663 issued
Feb. 28,
1978 to Masuda et al, U.S. Pat. No. 4,286,082 issued Aug. 25, 1981 to
Tsubakimoto
et al., U.S. Pat. No. 4,062,817 issued Dec. 13, 1977 to Westerman, and U.S.
Pat. No.
4,340,706 issued Jul. 20, 1982 to Obayashi et al. The absorbent capacity of
such
high-absorbency materials is generally many times greater than the absorbent
capacity
of fibrous materials. For example, a fibrous matrix of wood pulp fluff can
absorb
about 7-9 grams of a liquid, (such as 0.9 weight percent saline) per gram of
wood pulp
fluff, while the high-absorbency materials can absorb at least about 15,
preferably at
least about 20, and often at least about 25 grams of liquid, such as 0.9
weight percent
saline, per gram of the high-absorbency material. U.S. Pat. No. 5,601,542,
issued to
Melius et al., discloses an absorbent article in which superabsorbent material
is
contained in layers of discrete pouches. Alternately, the sup erabsorbent
material may
be within one layer or dispersed throughout the substrate.
Cleaning Implement
[0049] In an embodiment of the invention, the cleaning composition may be used
with a cleaning implement. In an embodiment of the invention, the cleaning
implement comprises the tool assembly disclosed in U.S. Patent No. 7,386,910,
entitled
"Cleaning Tool with Gripping Assembly for a Disposable Scrubbing Head", filed
Sept.
30, 2003. In another embodiment of the invention, the cleaning implement
comprises the
tool assembly disclosed in U.S. Patent No. 7,065,825, entitled "Cleaning Tool
with
Gripping Assembly for a Disposable Scrubbing Head", filed June 23, 2003. In
another
embodiment of the invention, the cleaning implement comprises the tool
assembly
disclosed in
CA 02672748 2014-04-02
U.S. Patent No. 6,953,299, entitled "Interchangeable Tool Heads", filed
January 27,
2004. In another embodiment of the invention, the cleaning implement comprises
the tool
assembly disclosed in U.S. Publication No. US 2005/0217698, entitled
"Ergonomic
Cleaning Pad", filed April 1,2004. In another embodiment of the invention, the
cleaning
implement comprises the tool assembly disclosed in U.S. Patent No. 7,065,838,
entitled
"Locking, Segmented Cleaning Implement Handle", filed May 19, 2004.
Wipes Dispenser System
[0050] Suitable wipes dispenser systems include both individually packaged
disinfectant wipes and bulk packaged one or more disinfectant wipes or other
suitable
disinfecting articles. The dispenser system suitably comprises a sealable
container,
which is substantially impervious to both liquid and/or gas. The term
"container",
refers to, but is not limited to, packets containing one or more individual
wipes and
bulk dispensers, such as canisters, tubs and jars, which dispense one
disinfectant wipe
at a time, and further feature suitable means to reseal the bulk dispenser
between uses
to preserve the integrity of the disinfecting articles. One example is a
cylindrical
canister dispenser that hosts a roll of individual wipes, separated by
perforations to
permit the tearing off of individual wipes for use. Such dispenser is
conveniently
gripped by the user and held in position while the user removes a wipe.
Suitable
dispensers feature a resealable dispensing cap and orifice (See, e.g., Chong,
U.S.
6,554,156, of common assignment) that dispenses individual wipes from a roll
and
retains the next wipe in a ready-to-dispense position, yet allows sealing of
the dispensing
cap to close the container against the environment when not in use. A further
example,
within the scope of the present invention, is to package individual wipes in a
non-linked
manner, in a dispenser permitting their removal one at a time, as is the case
with many
wipe/dispenser combinations known in the art.
[0051] Wipe dispensers are convenient items that provide moistened sheets or
wipes
for a variety of uses. Typically, wipes are formulated for specific purposes
that
include infant wipes, personal care wipes, dishwashing wipes, hard surface
treatment
wipes, disinfectant wipes, cosmetic or sanitary wipes, hand wipes, wipes used
in car

cleaning, household or institutional cleaning or maintenance, computer
cleaning and
maintenance and any other area in which a flexible substrate having a useful
liquid
treatment composition has application.
Directions for use
[0052] In one embodiment, the directions include wiping the surface clean with
the
wipe and letting air dry. In one embodiment, the directions include wiping the
surface, using enough wipes for the treated surface to remain visibly wet for
30
seconds or 1 minute or 2 minutes or 4 minutes, and letting the surface dry.
For highly
soiled surfaces, it may be necessary to clean excess dirt first. In one
embodiment, the
directions include wiping the surface to be disinfected with a wet cleaning
wipe and
allowing the surface to dry.
EXAMPLES
[0053] In Table I, the formulas were loaded onto wipe substrates with a 3.75
loading
ratio. The wipe substrates were then wiped on glass mirrors and allowed to
dry.
Testing was also done on black enamel and ceramic tile surfaces. The examples
show
the results on mirrors, which were visually examined for filming and streaking
and
graded from very low filming/streaking to low to medium to high. The C8-C10
alkylpolyglucoside is superior to the amine oxide.
